Privacy Policy
Effective 16 September 2026 · Applies to the First Fork app for iPhone and Apple Watch
First Fork is a glucose logger for gestational diabetes. It is built so that everything you log stays on your device. We do not have user accounts, we do not run advertising or crash-reporting SDKs, and we do not operate a server that your health data passes through. We count how many people reach each screen of the first-run setup — a total only, with nothing attached that could identify you. This page explains exactly what the app stores, what leaves your device, and your choices.
What stays on your device
Every reading, meal window, target range, and medication note you log is stored locally on your iPhone, in a database shared only with the First Fork Lock Screen/Dynamic Island Live Activity and Apple Watch app you use — never with a server. This data is included in your iCloud or iTunes device backup if you have backups turned on, under Apple's own backup terms; First Fork itself has no cloud sync and cannot see your data.
Meter photo scanning. If you photograph a glucose meter to log a reading, the photo is read on your device using Apple's on-device text recognition (Vision framework). The photo and its text are processed locally and are not uploaded anywhere.
What leaves your device
| When | What happens | Where |
|---|---|---|
| You subscribe or buy Lifetime | Your purchase is handled entirely by Apple through StoreKit | Apple |
| You export or share the clinic PDF | You choose the destination (Messages, Mail, AirDrop, Print, Files, etc.) through iOS's share sheet | Wherever you send it — that is your choice, not ours |
| You reach a screen during first-run setup | The app adds 1 to a counter for that screen. The entire message is the screen's name and the app version — for example {"step":"reminders","appVersion":"1.0.0"} | A server we run at Cloudflare |
We receive only an anonymous confirmation from Apple that a purchase is active. We never see your payment details, Apple ID, or name. The clinic PDF is generated on your device and only leaves it when you actively choose to export or share it.
Setup screen counts
When you first set up First Fork, the app tells our server which setup screen you reached, so we can see where the setup is confusing and fix it. We want to be precise about how little this is.
What is sent: the name of the screen and the app's version number. That is the whole message. There is no account, no device identifier, no advertising identifier, no session identifier, and no random id of any kind. Your IP address is never stored.
What is stored: a running total per screen, per app version, per day — one number that goes up by one. We do not store a record of your visit, so there is no row anywhere that represents you, and nothing that could be assembled back into your path through the app. We can see that 300 people reached a screen; we cannot see whether you were one of them.
What is never sent: no reading, no meal, no time, no target, no note, no medication, no name, and no due date. Nothing you log is involved in this, ever.
Each screen counts at most once per install, so this stops entirely once you have finished setting up. Counting is off in test builds, including TestFlight — only the App Store version counts.
What we do not do
- No user accounts, sign-in, or email collection.
- No advertising, no ad identifiers, no tracking across apps or websites.
- No third-party analytics or crash-reporting SDKs of any kind. The setup screen counts described above are our own, and are totals with no identifier attached.
- No profiles, no cohorts, no per-person records, and no way to follow one person's path through the app.
- No servers that your readings, meals, or notes are ever sent to.
- No Apple Health (HealthKit) integration in this version — First Fork does not read or write Health data.
- No selling, renting, or sharing of personal data, because we never receive any.
Notifications
If you allow notifications, First Fork schedules them locally on your device for your two-hour post-meal windows. No notification content passes through a server.
Not medical advice
First Fork is a logging and organizing tool. It does not diagnose, treat, or provide medical advice, and it is not a substitute for guidance from your clinician. Always follow your care team's instructions for testing, targets, and treatment.
Children
First Fork is made for pregnant adults managing gestational diabetes. It is not directed at children under 13, and we do not knowingly collect information from them.
Your choices and rights
- See or delete your data: everything First Fork holds is on your device, in Settings and your reading history. Deleting the app deletes it.
- Subscriptions: manage or cancel in iOS Settings → Apple Account → Subscriptions. Refunds are handled by Apple.
- If you are in the EEA, UK, or California, you have rights to access, correct, delete, and object to processing of personal data; because First Fork holds no personal data outside your own device, these rights are exercised directly on your device as described above.
Changes to this policy
If this policy changes, we will update the effective date above and, for material changes, note it in the app's release notes.
